Mode: changes the way OpenLog behaves on powerup. The default, 26, is CTRL-Z.Įsc#: the number of times you need to enter the above character to enter command mode. You can edit this file in-place with a text editor, and the next time the OpenLog is powered up, it will use the new settings.īaud: a standard communications rate 115200 is the max, 9600 is the default.Įscape: the ASCII character used to switch from logging mode to command mode (see below). If you edit this file, you will see that it contains a set of comma-separated numbers, followed by a text legend: 9600,26,3,0,1,1 Config fileĪfter you use the OpenLog at least once and examine the micro-SD card, you will find a file called CONFIG.TXT on it. You can edit the config file on the micro-SD card, or you can access the built-in command mode. There are two ways to configure the OpenLog.

COOLTERM SAVE SERIAL MONITOR AS TEXT FILE SERIAL
You can use a terminal program to connect directly to the OpenLog, and use the "command mode" to dump the data over the serial link. Open it with a text editor, and you'll see all the text that was sent to the OpenLog!
The OpenLog will create a new file each time it powers up the highest-numbered file is the most recent log. When you examine the card with your computer, you will see one or more files on the card named e.g. This delay gives the OpenLog a chance to write the last partial buffer of data to the card. To ensure that you get the last bit of data, wait five seconds after the last data is sent before powering down. Power down the OpenLog before removing the micro-SD card. You can pull out the micro-SD card and read it with your computer. There are two ways to retrieve data from the OpenLog: If you haven't soldered before, it's easy, see our tutorial on the basics. If you'd like to plug it into a male FTDI header as found on many of our products, we recommend using a 6-pin, right-angle female header ( PRT-09429). You can solder any headers or bare wires you like to the OpenLog. FTDI Crossover Board and right-angled headers.FTDI Basic Breakout and mini-USB cable, or FTDI cable.Open it on your computer, and you'll see all the text that was sent to the OpenLog! The OpenLog will create a new file each time it runs the highest-numbered file is the most recent log. There should be one (or more) files on the card named e.g. Remove the micro-SD card from the OpenLog, and look at it on your computer.

This could be sensor readings, GPS data, warnings, anything. Plug a micro-SD card into the socket on the back of the OpenLog.Ĭonnect a power supply (3.3V to 12V) to the VCC / GND headers.Ĭonnect your project's serial output (9600 baud TTL-level) to the RXI header. Solder your desired headers to the OpenLog (see below). Here's one way to use an OpenLog with the factory-default settings, but note that the OpenLog is very versatile and supports other settings and ways to connect to it.
